I had a Super Scanner Antenna (Antenna Specialist model MS-119) back in the 80's & 90's. However, when I returned from college, to my horror, I found that my parents had it dismantled (read destroyed) when they did a remodel of the house. I had it 40 feet and was by far the best antenna I had used. I had previously used Sigma 5/8, AstroPlane (which was great for skip) and a Mako 1/4 wave. I used it both on 11 and 10m with no significant change in SWR
$50 for a complete super scanner is a HELLUVA deal, provided the antenna is complete, with control box and the switching relay box. Fully restored units on eBay typically go for about $275-350.00 and the rare NOS can fetch as high as $450.00 Non-restored antennas can be found for about $125-175.00 I have been watching the market and am now interesting in reuniting my 2000gtl with a superscanner
I also seemed to remember -also to my horror- there being a website that showed how to cannibalize 11m super scanner to work at 2m.
I will echo the previous poster in saying that if you don't buy it, I will!
